Caution

Do not install the projector in locations that are subject to excessive water, humidity, steam or oily smoke. Doing so may result in fire, malfunction or electric shock.

NOTES ON USE

1 The projector uses a high-voltage mercury lamp under high internal pressure.
This lamp may break, emitting a popping sound, or fail to illuminate, due to impact or extended use.

2 The high-wattage lamp becomes very hot during operation. Please observe the following precautions:
• Never place objects on top of the projector while it is in operation.
• Make sure there is an unobstructed space of 1,000 mm (39-3/8 in) or more around the projector’s exhaust openings.
• If stacking projector units, care must be taken to provide the recommended space between units. These space requirements also apply to installation
where only one projector unit is operating at one time and the other unit is used as a backup.
• If the projector is placed in a box or enclosure, the temperature of the air surrounding the projector must match the operating temperature listed in the
specifications table during use. Also, make sure the projector’s intake and exhaust openings are not blocked. Ensure there is sufficient ventilation to
prevent hot air from the exhaust openings being recirculated into the intake opening.

3 The lamp replacement cycle duration becomes shorter if the projector is operated repeatedly for short periods.
• The lamp replacement cycle varies greatly depending on individual lamp characteristics and usage conditions.
• The brightness of the lamp will gradually decrease with use.

4 Due to natural characteristics of lamps, screen brightness may fluctuate. This is not an indication of faulty lamp performance.
